Install the notification client:
sudo pacman -S --needed libnotify
Many desktop managers (KDE, Gnome, etc.) have their own built-in notification server. In other desktop environments, a notification server needs to be manually installed. For example, in hyprland we may use [[mako]]. After installing a notification server, test libnotify with
notify-send "My message here"
You should get a message on your desktop.
